  5 P's of Cold Weather Preparedness
During Dense Fog, An Ice Storm, Or Snow
Stay Informed and Connected:
  • Sign up for ALERTJAX notifications and follow JaxReady on Twitter, Facebook, and Nextdoor.
  • Check local news for detailed information and follow instructions carefully
  • Know how to contact your loved ones, at work, at school, and at home.
  • Follow the instructions of emergency officials. 
Be Careful on the Road: 
  • Listen to emergency personnel and do what they say.
  • Stay off the road as much as possible.
  • If you must drive, use extreme caution during icy or foggy conditions. 
  • Take extra care on elevated roads, like bridges.
Prepare for Power Outages: 
  • Keep generators outside and at least 20 feet away from your home.
  • Stay warm: wear warm clothes and go to a public place like a library, recreation center, or mall for temporary relief.
  • Use flashlights, not candles for light.
  • Preserve cell phone battery life. Texting saves battery life compared to calling.
